My autos are turning into flowering. It seem I’m under led, respecting the grow schedule and new leaves are turning light green… is it normal or a deficiency/excess (iron?) ? Thank you for the answers

This is absolutely normal.. all new growth is that light green and it will darken up to "normal" as it gets older... no worries!

Nutrient lockout, ph imbalance or nutrient burn?
Unfortunately I don't have a ph meter, so my best guess is one or more of these problems: nutrient lockout, ph imbalance or nutrient burn. The first 3 photos are from an Auto Northern Light and the last 2 are from an Auto Jack Herer.

Soil pH is surprisingly high. What's the best/safest way to lower soil pH (without eliminating nutrients from dry amendments)
Granite Runtz #2's leaves have started to lighten in color & develop rust spots/mottling. Troubleshooting this, my soil pH is in mid 7s; I always pH water to 6.4-5. Will daily watering with ~pH 6.0-2 be enough to lower soil pH sufficiently? I wonder if this also affected growth?

Brown spots on lower leaves - ph fluctuations?
I have discovered some brown spots on the lower leaves. I suspect it might be down to ph fluctuations - first time growing DWC so probably my bad! Does anyone agree? I should also add - I did a nutrient change a few days ago and for the first time added calmag & silicon

Yellowing new growth.Normal or should i be doing something?
Might be an overreaction but i am noticing all my new growth is yellowing. Could it be a high/low temp fluctuation imbalance during the night/day cycle? Is it a problem? Should i be doing something to fix it? Im 2 days into flower.

Deficiency?
My current grow is on its 5th week of flower and many lower leaves on each plant have begun to yellow then develop brown spots. I’ve did a little bit of research and I think it could be a nitrogen deficiency. Any help is appreciated.
